A mammogram is a medical procedure that employs a dedicated mammography x-ray unit to conduct a low-dose x-ray examination of the breast tissue. Mammograms are instrumental in the early detection of breast cancer, often before any visible signs or symptoms of the disease become apparent.
There are two primary types of mammograms available: 2D and 3D mammograms. In the case of a 2D mammogram, it captures breast images in two dimensions, typically taking two pictures of each breast—one from the side and another from above. This method is suitable for patients with larger lumps or non-dense breast tissue.
Conversely, a 3D mammogram, also referred to as digital breast tomosynthesis, involves the capture of a series of images taken from various angles across the breast. These images are then computationally combined to generate a comprehensive 3D representation of the breast. This advanced technique enables healthcare professionals to visualize the breast in greater detail.
3D mammography can offer more precise information regarding early-stage invasive breast cancers compared to 2D mammography alone. It is also particularly valuable for individuals with dense breast tissue or breast implants.
